Application filed March 14, 1914. Serial No. 824,644.

To aZZ whom it may concern:

Be it known that I, VILLIAM W. FnAzIEn, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented new and useful Improvements in Rolling-Mills, of which the following is a specification.

My invention relates broadly to rolling mills, but more particularly to rolling mills with vertical rolls.

The principal object of my invention is to provide for the vertical rolls of a rolling mill a pair of lateral guides to insure an easy and straight entrance of the metal to be rolled between the said rolls. I prefer to have the guides move laterally in and out automatically as the vertical rolls are adjusted.

I have shown my invention applied to a rolling mill of the universal type, but it may be used wherever adjustable rolls require adjustable guides for the metal to be rolled.

My invention relates also to the details of the mechanism for adjusting the guides.

Referring to the accompanying drawings, Figure 1 is a top plan view of a universal mill equipped with my invention, parts being broken away; Fig. 2, a side elevation of Fig. 1 with parts broken away and in vertical section; and Fig. 3, a vertical section on the line HII1I of Fig. 2.

On the drawings, I show a pair of roll housings 1 in which are mounted the horizontal rolls 2 and the vertical rolls 3, the latter being spaced apart to engage and roll the vertical edges of the metal being rolled while the rolls 2 are arranged to roll the horizontal faces of the said metal. The necks at of the rolls 3 are mounted in the bearings 5 which are adjusted horizontally away from the adjacent housings 1 by the vertical bars 6 having their ends lying between the bearings 5 and the ends of the screws 7 in the housings. The moving of the screws 7 toward the bars 6 causes the vertical rolls 3 to move toward each other, or the center of the pass between them. The screws 7 extend beyond the outer faces of the housings 1 and are provided with the spur gears 8 which rotate the screws, but permit the screws to travel lengthwise through them by reason of the spline 9 in the gears extending into the longitudinal grooves 10 in the screws.

11 is an idler gear connecting the gear wheels 8. The gear-Wheels are driven in any desired manner, as by applying power to the lower gear wheel 8.

12 is a horizontal shaft lying over the upper ends of the rolls 3. On this shaft are two bevel-gear wheels 13, one over each roll 3 meshing with the bevel gear wheel 14: on the upper end of the adjacent roll 3. Each bevel gear wheelhas an extension on the shaft 12 provided with the annular groove 15 in which the fork or projection 16 on the upper end of the adjacent bar 6 lies. The gears 13 are slidable on the shaft 12 but are rotated therewith. It is thus seen that, when the bars 6 are caused to travel the bearings 5 and the gears 13 and 1% travel with the bars and with the rolls 3, thereby keeping the gears 13 and 14 in mesh. It is seen that the forks or projections 16 by engagement with the outer walls of the grooves 15 prevent the gears 13 and 14% from getting out of mesh. The shaft 12 is driven by any convenient power connection, not shown.

17 represents the rollers of a feed table on which the metal travels to the rolls.

To the ends of the mill-housings 1, 1 secure the brackets 18, which support the bearings 19 for the screws 20, which have thereon the collars 20 bearing against the inner face of the bearings 19 to prevent the outward movement of the screws. 21 is a spur gear secured to the outer end of each screw and meshing with the idler gear 11. Both screws 20 adjust the aforesaid guides by the same mechanism, so that a description of one of these mechanisms will be sufficient. referring to Fig. 2, the mill housings 1 are each provided with a horizontal opening 22 for the fixed bushing 23, it being understood that the housings 1 shown on Fig. 1 are constructed alike with respect to the details shown on Fig. 2. The sleeve 21 is slidable in the sleeve 23 but prevented from rotation therein by the spline 25 seated in registering longitudinal grooves in the two sleeves. The sleeve 24 has an axial opening 26,'the outer end thereof being enlarged and threaded to receive the bushing 27 having exterior threads meshing with the threads in the enlarged portion of the opening 26, and internal threads meshing with the screw 20, having its inner end in the smaller portion of the opening 26. The bushing 27 is prevented from rotating by the cross-key 28 extending transversely through the sleeve and the bushing 27. To the inner end of the sleeve 2% is secured the head 28 to which one of the guides 29 is rigidly secured. On Fig. 1 it is seen that the two guides 29 have their parts 30. opposite the heads 28 substantially parallel and in line with the inner edge of the adjacent roll 3 or slightly back of the said edge (Fig. 2). The guides 29 extend forwardly over the rollers 17, and converge toward the said parallel parts 30. The threads on the screws 20 are so cut in proportion to the ratio of the gears to each other and to the pitch of the threads onthe screws 7 as to give the guides 29 thesame horizontal travel that the vertical rolls receive.

In case it is desired to use the mill without the vertical rolls, in order to roll wider plates than the distance between the vertical rolls it is not necessary to remove the guides 29, since it is only necessary to bring the guides back toward the mill housing beyond the edges of the metal to be rolled. It will be noted that the converging sides'of the guides 29 will direct the metal to be rolled toward the center of the roll pass, and that the parallel portions 30 of the guides will square the said metal so that it will not pass diagonally between the rolls.

I do not desire to be restricted to the de tails and combinations described and shown but desire to cover such modifications thereof as come within the scope of the appended claims.

I claim 1. In a rolling mill, a pair of vertical rolls, screws for adjusting the width of the pass between the rolls, a guide in front of each roll for the metal to be rolled, screws for automatically adjusting the guides with respect to each other and means driving all the said screws so as to cause each roll and its associated guide to move simultaneously toward the other roll and its associated guide.

sleeve to support each guide, a screw for causing each sleeve to slide in order to adjust the guide supported thereby, and means connecting the said roll adjusting means and the said screw for causing each roll and its associated guide to travel. simultaneously and in the same direction;

3. In a rolling mill, a pair of vertical rolls, means for adjusting the width of the pass between the rolls, a guide in front of each roll arranged to direct metal to be rolled into the pass between the rolls, a slidable sleeve to support each guide, a screw for causing each sleeve to slide in order to adjust the guide supported thereby, and means connecting the said roll adjusting means and the said screw for causing each roll and its associated guide to travel simultaneously and in the same direction, the threads on the screws being so cut and the said connections being so proportioned and arranged as to cause each roll and its associated guide to maintain fixed relations at all adjustments.

at. In a rolling mill, a vertical roll, a guide in front thereof for the metal to be rolled, and intergeared separate means for simultaneously moving the roll and the guide in the same direction and equal distances.

5. In a rolling mill, a pair of vertical rolls, a pair of screws for adjusting the width of the pass between the rolls, gears for rotating the screws, a guide in front of each roll, a screw for adjusting each guide, and gearing connecting each of the last named screws with one of the first named gears.

6. In a rolling mill, a vertical roll, a guide in front of the roll, a slidable non-rotatable sleeve to which the guide is connected, a nut on the sleeve, a screw in the nut, and means for simultaneously moving the roll and the guide horizontally in the same direction.
